  • Build and tune lexical, semantic, vector, and neural hybrid retrieval, including embeddings, blend weights, thresholds, boosting, filters, facets, synonyms, and fallback behavior.
  • Use signals and behavioral data to improve relevance, recommendations, personalization, and popular or successful results.
  • Create relevance benchmarks, automated regression tests, citation and grounding tests, latency targets, and per-query cost measures.
  • Troubleshoot ingestion, indexing, Solr, Kubernetes/AWS, APIs, pipelines, model endpoints, and front-end integrations.
• Conversational Search and Generative Ai
  • Engineer single-turn and multi-turn search flows with intent recognition, entity extraction, query rewriting, clarification, and session context.
  • Implement grounded RAG that retrieves approved sources, cites evidence, and suppresses or falls back when evidence or confidence is insufficient.
  • Integrate with enterprise LLM services and Client AI Gateway using prompt controls, model configuration, rate limits, error handling, latency budgets, and cost governance.
  • Tune experiences for product numbers, specifications, availability, certificates, manuals, application notes, and related support content.
  • Apply guardrails for transactional or product-SKU queries, low-confidence grounding, and zero-result scenarios. 
• Integration, Delivery, and Operations
  • Partner with AEM and front-end engineers to deliver accessible search results, conversational answers, follow-up suggestions, and facets aligned with the Client Design System.
  • Manage Fusion configuration as code through GitLab, peer review, automated testing, and CI/CD practices.
  • Instrument click-through, zero-result, no-click, reformulation, abandonment, task completion, latency, and pipeline-health metrics.
  • Produce architecture diagrams, deployment documentation, runbooks, configuration standards, and knowledge-transfer materials.
  • Work with security, privacy, legal, architecture, product, content, and business teams on access controls, data handling, AI guardrails, and release readiness.
  • Participate in Client AI-DLC and Agile delivery cadence.

• Bachelor's degree in Computer Science, Information Systems, Engineering, Data Science, or a related discipline, or equivalent practical experience.

• Hands-on knowledge of schemas, analyzers, tokenization, synonyms, faceting, boosting, filtering, relevance scoring, query debugging, connectors, signals, custom pipeline stages, and REST APIs.
• Practical experience with semantic search, embeddings, approximate nearest-neighbor retrieval, neural hybrid ranking, relevance evaluation, RAG, grounding, prompt design, citations, guardrails, and fallback patterns.
• Experience with multi-turn context, session design, intent classification, and entity extraction.
• Experience deploying or operating search workloads in AWS and Kubernetes, including observability and production troubleshooting.
• Proficiency in Java and/or Python, JSON, HTTP APIs, Git, automated testing, and CI/CD.
• Ability to convert customer journeys and business requirements into technical designs, backlog items, acceptance criteria, and measurable outcomes.
• Clear communication with technical and nontechnical stakeholders; able to work independently, prioritize competing work, resolve ambiguity, and transfer knowledge

• Lucidworks Fusion 5.x implementation, upgrade, or administration experience in a self-hosted environment.
• Experience with Fusion AI, RAY, Learning-to-Rank, Relevance Workbench, Analytics Studio, Commerce Studio, A/B testing, or equivalent capabilities.
• Integration experience with AEM as a Cloud Service, commerce, product catalogs, digital assets, or certificate/document services.
• Knowledge of Redis or another session store; multilingual search; part-number/SKU handling; permissions-aware retrieval; and structured/unstructured content blending.
• Experience in compliance-sensitive or document-intensive environments, plus familiarity with accessibility, privacy, secure AI development, responsible AI, and production monitoring.
